<p>PURPOSE:To obtain an ethylene-vinyl acetate copolymer saponificate having excellent adhesiveness and its original melt fluidity and molding processability, by adding polyvinyl alcohol to the saponificate. CONSTITUTION:One hundred pts.wt. saponificate (having a saponification degree of 5-100mol%) of an ethylene-vinyl acetate copolymer containing approx. 65- 99.7mol% ethylene and a melt index of approx. 0.1-500g/ten min is mixed with 0.1-50pts.wt. polyvinyl alcohol having a polymerization degree of approx. 300- 3,000 and a saponification degree of approx. 70-100mol%, and then the mixture is kneaded at approx. 120-200 deg.C to obtain an adhesive resin composition.</p> |
